BSF frass: What goes around comes around ♻️
One of the most overlooked outputs of BSF farming? Organic fertilizer. Alongside protein production, BSF systems also generate frass which is a nutrient-rich organic fertilizer created during the rearing process.
Insect frass naturally contains:
→ organically bound nitrogen
→ beneficial microorganisms
→ chitin, which can support plant resilience and soil health
In previous cultivation trials, soybeans grown with insect fertilizer showed up to 17% higher yields compared to conventional approaches.
As insect farming scales, circular by-products like organic fertilizer will become an increasingly important part of the agricultural value chain, turning nutrients back into food production instead of waste and once more closing the local protein loop.
Here’s a sneak peek from one customer’s field where WURMGOLD just arrived, our insect-based fertilizer produced from BSF frass fed on pre-consumer organic by-products.
